Methods

batchGetItem({required Map<String, KeysAndAttributes> requestItems}) → Future<BatchGetItemOutput>
Retrieves the attributes for multiple items from multiple tables using their primary keys.
batchWriteItem({required Map<String, List<WriteRequest>> requestItems}) → Future<BatchWriteItemOutput>
Allows to execute a batch of Put and/or Delete Requests for many tables in a single call. A total of 25 requests are allowed.
close() → void
Closes the internal HTTP client if none was provided at creation. If a client was passed as a constructor argument, this becomes a noop.
createTable({required KeySchema keySchema, required ProvisionedThroughput provisionedThroughput, required String tableName}) → Future<CreateTableOutput>
Adds a new table to your account.
deleteItem({required Key key, required String tableName, Map<String, ExpectedAttributeValue>? expected, ReturnValue? returnValues}) → Future<DeleteItemOutput>
Deletes a single item in a table by primary key.
deleteTable({required String tableName}) → Future<DeleteTableOutput>
Deletes a table and all of its items.
describeTable({required String tableName}) → Future<DescribeTableOutput>
Retrieves information about the table, including the current status of the table, the primary key schema and when the table was created.
getItem({required Key key, required String tableName, List<String>? attributesToGet, bool? consistentRead}) → Future<GetItemOutput>
Retrieves a set of Attributes for an item that matches the primary key.
listTables({String? exclusiveStartTableName, int? limit}) → Future<ListTablesOutput>
Retrieves a paginated list of table names created by the AWS Account of the caller in the AWS Region (e.g. us-east-1).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putItem({required Map<String, AttributeValue> item, required String tableName, Map<String, ExpectedAttributeValue>? expected, ReturnValue? returnValues}) → Future<PutItemOutput>
Creates a new item, or replaces an old item with a new item (including all the attributes).
query({required AttributeValue hashKeyValue, required String tableName, List<String>? attributesToGet, bool? consistentRead, bool? count, Key? exclusiveStartKey, int? limit, Condition? rangeKeyCondition, bool? scanIndexForward}) → Future<QueryOutput>
Gets the values of one or more items and its attributes by primary key (composite primary key, only).
scan({required String tableName, List<String>? attributesToGet, bool? count, Key? exclusiveStartKey, int? limit, Map<String, Condition>? scanFilter}) → Future<ScanOutput>
Retrieves one or more items and its attributes by performing a full scan of a table.
toString() → String
A string representation of this object.
inherited
updateItem({required Map<String, AttributeValueUpdate> attributeUpdates, required Key key, required String tableName, Map<String, ExpectedAttributeValue>? expected, ReturnValue? returnValues}) → Future<UpdateItemOutput>
Edits an existing item's attributes.
updateTable({required ProvisionedThroughput provisionedThroughput, required String tableName}) → Future<UpdateTableOutput>
Updates the provisioned throughput for the given table.

Operators

The equality operator.
